After serious consideration, Professor Kong Zhemin asked: "Can it be understood as a popular science textbook for ordinary people?"
Yu Pingan nodded: "Yes, you can understand it that way.
"We want to use the Internet to allow more people to see these contents and provide more efficient retrieval methods.
"At the same time, in terms of the content of the compilation, it is not too esoteric and professional for ordinary people to understand; neither is it too empty, vulgar, and useless.
"That is why I'm here, hoping to invite you to collaborate.
"You are not only an expert in the industry but also a professor who is loved by students, and you have a wealth of experience in writing textbooks. It is absolutely foolproof to have you to quality check these contents."
Professor Kong Zhemin was a little surprised.
"It sounds like a great thing for the future.
"However, this seems to be a very large project."
